iPhone 5 powers on but in recovery mode but won't recover
I had a good friend and customer come in today with their iPhone 5 (A1429) and they are telling me that while the battery was low and they plugged it in, the phone wouldn't charge and it rebooted in recovery mode.
I took it and tried doing recovery but I get error 9. The process goes well to about a reboot, shows the apple logo and the process line, but then half the screen goes black and it reboots asking to be connected to iTunes again, which iTunes shows error 9.
Any suggestions? I have yet to open it but I was thinking that possibly its the connector? as error 9 refers to loss of power on usb. I might be wrong and thought maybe someone here had similar issue.
I've also thought about a bad logic board but I would hate to tell my client / friend that he can try and locate one that clean for $300..
Any suggestions are welcome.. I've done all kinds of resets, and different computers for the recovery with no success.
Thank you in advance.
